re bonjour, j'essaie de faire au mieux mais je pars de très bas...
J'ai tapé la commande décrite dans le wifi check dans le terminal et j'ai eu tout ça . Je mettrais bien des balises pour vous faciliter la tache mais je ne sais pas où les placer... tout ce qui suit c'est du chinois ! j'ai fait le wificheck en étant connecté avec la prise dongle usb. (peut-être qu'il ne fallait pas ?).
Merci pour vos présentes et futures explications..
